Which statement about fire department radio communications is correct?

• A. Most departments use ten-codes for radio communications.
• B. Most departments use clear speech/plain English for radio communications.
• C. Radio communications are not automatically recorded.
• D. Ten-codes are never problematic during multi-jurisdictional operations.

Answer: (B)

Clear, plain English is the standard for fire department radio communications because it eliminates ambiguity and speeds understanding, especially when multiple units or agencies are involved. Ten-codes can vary between departments and regions, so what one unit means by a code may be misunderstood by another during multi-jurisdictional operations. Speaking in clear, concise language ensures everyone hears the same message, can respond accurately, and can confirm details quickly. In many departments, radio communications are automatically recorded, so using plain language also makes transcripts easy to follow and review later. The other statements aren’t as reliable: ten-codes aren’t universally used or problem-free across agencies, and assuming communications aren’t recorded isn’t generally correct.
